“A Yooperlite is a syenite rock rich in fluorescent sodalite that glows a bright orange, yellow, or pink under ultraviolet (UV) light. Discovered in 2017 in Michigan's Upper Peninsula by rockhound Erik Rintamaki, these stones look like ordinary grey rocks in daylight but light up like burning embers in the dark when scanned with a 365nm UV flashlight.”
